Series LM Meniscus Lenses

SERIES_LM_full

Meniscus lenses allow minimal spherical aberrations when a parallel beam enters the convex surface. This results in a minimum focal spot size for the incoming collimated light source. All meniscus lenses shown have positive focal lengths. Negative focal lengths are available upon request.

All series LM lenses are coated and optimized for use at 10.6 microns.
